RESIN SEALED STRUCTURE FOR LED

摘要

PURPOSE:To retard exfoliation of epoxy resin from a printed board. CONSTITUTION:A printed board 11 is fixed to the back face side of a light reflecting case 10 having a hole 10a for fixing an LED element and 8 pair of bonding pads 12, 13 are provided on the substrate 11 in the hole 10a while a LED element 14 is fixed to the pad 12. The LED element 14 and the pad 13 are connected through a wire 15 and the hole 10a is sealed with epoxy resin 16 thus providing the pads 12, 13 with a complex pattern for increasing adhesion area between the epoxy resin 16 and an exposed face 11a of the substrate.
